FREDERICK L. KI KRRIDE, OF'WYANDOTTE, KANSAS, ASSIGNOR on TWO- THIRDS TO ROBERT H. DRENNON AND WILLIAM G. DUVALL, BOTH or KANSAS CITY, MISSOURI.

GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 279,255, dated June 12, 1883.

Application filed March 27,1883. (No model.)

' dotte and State of Kansas, have invented a new and useful Improvement in Doors for Grain- Cars, of which the following is a full, clear, and

j exact description, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents the side elevation of a grain-car with my improved door in position. Fig. 2 shows the inside of the car with the door raised and partially moved to one side. Fig. 3 is a section throughw w of Fig. 1. Fig. 4 is a section through 11 y of Fig. 2. Fig. 5 are details to be referred to. Fig. 6 is a horizontal section, showing to the eye, looking up, the under side of the rail D, a space being left at 'the left to permit the hanger G to pass.

My invention relates to the doors of railway-cars for transporting grain, and the object is to produce a door that can be easily handled, and when closed cannot possibly be opened by the motion or jostling of the cars.

It consists in the novel combinations of devices hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have car ried it out.

In the drawings, A represents a grain-ear, andBthe door. This door should be made of a double thickness of lumber, with the lumber running in different directions to give it brace, strength, and tightness. The upper and lower edges of the door are also provided with the metal guards I) b for their protection. At the center of the lower edge of the door I secure the metal lift 1), into which may be introduced the end of a lever-bar for raising or lifting the door against the pressure of the grain .on the inside. On the inner face of the door I secure the metal hanger G, which, when the door is raised, catches on an upper metal track, D, along which it slides, and supports the free side of the door the door is moved back within the car.

On eachside of the doorway I secure a metal guide, E, shaped as shown in Figs. 3 and 4. These guides are rigidly secured to the doorframe, andbetween them moves the door as it is raised or lowered, it being wholly between the jambs, and not, as usual, applied to the inside face. One of these guides is slotted to allow the door to pass through it when 5 being moved back, as shown in Fig. 2. The upper portion, 6, of the outside flanges ofthese guides is curved inward toward the top for the purpose of guiding the upper portion of the door inward in order to bring the hanger into position to move onto the metal track D as the door is moved to one side, and to bring the door itself within the body of the car, so that it can be moved back out of the way. A

lug or stop, F, on the inside of the car arrests ings inclosed within a casing,F. This casing I make about two inches wide and about nine inches long, more or less, and provide it with lugs f on its back, which are let into the door frame to prevent it from slipping from its place.

Inside of this casing, and on the lbwer end thereof, I secure a pivoted dog, G, as shown in Fig. 5, which catches on the.door B when down in position. Above this dog I arrange a sliding or adjustable wedgeshaped block,

H, slotted as shown in Fig. 5, which drops down between the dog and the outer edge of the casing F, and locks the door against any possibility of accidental opening fromthe motion of the car. hen the door is to be opened, the block H is raised, the dog drawn back, and the wedge allowed to fall on the opposite side of. the dog, which holds the dog out of the way until it is again desired to cure the door down.

Having thus dcscribedmy invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a grain-car, the door B, provided with the hanger G, in combination with the guides E, having the curved portion 6, and the track D, all constructed and arranged to operate substantially as and for the purpose set forth.

2. In a grain-car, the door B, in combina tion with the guides E, having the curved portion 6, substantially as and for the purpose set forth.

3. The casing F, provided with the lugsf,

in combination with the pivoted dog G and H, all constructed to operate substantially as I adjustable Wedge-block H, all constructed to and for the purpose set forth.

operate substantially as and for the pur ose set forth. v FREDERICK L. KIRKBRIDD. 5 4. I11 a grain-car the door B, provided with Vitnesses:
